If I have a list of data in cells A1:A150 (but the amount can vary), is there a way to push that into an array without looking at each cell individually to determine if it i
If you don't have empty cells in between it's actually pretty easy.
var lastRow = sheet.getLastRow();
var array = sheet.getRange('A1:A' + lastRow).getValues();
If you need to weed out empty entries after that, you can use a for statement, or to be faster, filter like an earlier answer shows.
var filteredArray = array.filter(function(n){ return n != '' });
The main difference between this answer and the one posted earlier that I mentioned is that getValues() will give you an array.
I've tested this and it works in google apps script, and it does not time out when I use the array, or even when I put in large amounts of data (I tested it with an array that has about 20-50 characters per entry and about 500 entries). Just make sure to define the var sheet or put in your own variable.
